TDS-4TM TDS & Temp Meter Video Transcript

Hey everyone, Tony the Filter Doctor here. Today we’re looking at the HM Digital TDS-4TM. Now, the TDS-4TM is a combination temperature and TDS meter. It comes from the factory pre-calibrated with a range of 0 to almost 10,000 parts per million, and it measures temperature from 0 to 80 degrees Celsius. It’s very accurate, plus or minus 2%, on either the TDS or the temperature reading. It has an auto shut-off feature, and uses two 1.5 volt button batteries, with an expected life of approximately 1,000 hours. Now, TDS meters are typically used by people who own an RO system or some other kind of demineralizing or deionizing system. But they are also very useful for those of you who are doing hydroponic gardening, or those of you with aquariums. Knowing the dissolved solids levels of your water is very important for either of those applications. Now let me zoom in here closely and show you what this looks like. Again, this is TDS-4TM from HM Digital, and I’m your host Tony, the Filter Doctor. Thanks for watching.
